Titel
Microstructure, mechanical properties and wear of Si3N4/TiN composites
Abstract
A number of particle-reinforced composites in the system Si3N4 /TiN were developed. Important results of strength-, KIc- and wear-measurements are: (1.) The strength and the KIc depend on the amount and grain size of the TiN-particles. (2.) For continuous turning of cast iron the TiN-containing materials exhibit under the used conditions a lower wear resistance than monolithic Si3N4-materials. (3.) Under the conditions of discontinuous turning of steel (depth of cut 1 mm) the wear resistance of the composites is significantly higher than for monolithic Si3N4.
